Operation; Maintenance - Makita M2400 Instruction Manual

Use the socket wrench provided to help assure proper
tightening.
• Always use only the proper inner and outer flanges
which are provided with this tool.
• Always lower the wheel guard after replacing the
wheel.
Securing workpiece (Fig. 9)
By turning the vise handle counterclockwise and then
flipping the vise nut to the back, the vise is released from
the shaft threads and can be moved rapidly in and out. To
grip workpieces, push the vise handle until the vise plate
contacts the workpiece. Flip the vise nut to the front and
then turn the vise handle clockwise to securely retain the
workpiece.
CAUTION:
• Always set the vise nut to the front fully when securing
the workpiece. Failure to do so may result in insufficient
securing of the workpiece. This could cause the
workpiece to be ejected or cause a dangerous
breakage of the wheel.
When the cut-off wheel has worn down considerably, use
a spacer block of sturdy, non-flammable material behind
the workpiece as shown in the figure. You can more
efficiently utilize the worn wheel by using the mid point on
the periphery of the wheel to cut the workpiece. (Fig. 10)
When cutting workpieces over 85 mm wide at an angle,
attach a straight piece of wood (spacer) to the guide plate
as shown in the figure. Attach this spacer with screws
through the holes in the guide plate. (Fig. 11)
If you use a spacer block which is slightly narrower than
the workpiece as shown in the figure, you can also utilize
the wheel economically when worn down the wheel.
(Fig. 12)
Long workpieces must be supported by blocks of non-
flammable material on either side so that it will be level
with the base top. (Fig. 13)

OPERATION

Hold the handle firmly. Switch on the tool and wait until
the wheel attains full speed before lowering gently into the
cut. When the wheel contacts the workpiece, gradually
bear down on the handle to perform the cut. When the cut
is completed, switch off the tool and WAIT UNTIL THE
WHEEL HAS COME TO A COMPLETE STOP before
returning the handle to the fully elevated position.
CAUTION:
• Proper handle pressure during cutting and maximum
cutting efficiency can be determined by the amount of
sparks that is produced while cutting. Your pressure on
the handle should be adjusted to produce the
maximum amount of sparks. Do not force the cut by
applying excessive pressure on the handle. Reduced
cutting efficiency, premature wheel wear, as well as,
possible damage to the tool, cut-off wheel or workpiece
may result.

Carrying tool (Fig. 14)
Fold down the tool head to the position where you can
attach the chain to the hook on the handle.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 15)
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 16)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
